ROTARY PRIME MOVER, MOTOR, COMPRE$SOR, PUMP, AND THE LEE.-

Applicationjled August 13, 1923. Serial No. 857,186.

To all whom it may concern Be it known that I, HARRY CLARENCE PHILLIPS, a subject of the King of Great Britain, residing at Gloucester, England, have invented certain new and useful Improvementsin and Relating to Rotary Prime Movers, Motors, Compressors, Pumps, and the like, of which the following is a specification.

This invention relates to rotary prime movers, motors, compressors, pumps, and the like, and has for its object to provide simplemeans by which power may be utilized or distributed to perform work in a most efficient manner. I

I The machine is of the type consisting of a horizontal cylinder within which is a rotor mounted eccentrically to the cylinder bore, the rotor being formed peripherally with a number of channels inwhich work radially slidable blades moving outward under centrifugal force so as to press against the wallof the cylinder when the rotor revolves.

Referring to the accompanying drawings illustrating a preferred construction,

Fig. 1 is a cross section of the rotor.

Fig. 2 is an: axial section.

Figs. 3, 4 and 5 are modifications in the form of the blades.

' In carrying the invention into effect with reference to Figs. 1 and 2, upon a shaft 1 is mounted a rotor 2 of cylindrical form having axially disposed'channels 3 open at the periphery, these channels extending from side to side thereof. Said rotor is eccentrically mounted in a cylinder 4 which is provided on opposite sides thereof with an inlet 5 and an outlet 6. Radially slidable within the channels 3 are blades 7 which are laterally tapered outwardly, and inwardly truncated so as to present concave faces 7 to the axis of the rotor 2. The sides of the blades 7 continuing inwardly from their tapering sides may assume a slight convexity 7 leading up to the said concave faces. As shown, the blades 7 are solid, but it is to be understood that they maybe chambered as desired.

S0 constructed, there is, at all times, a simple line-contact between each wall of each of the channels 3 and the corresponding wall or face of the blade 7 which slides therein, the line-contacts being substantially parallel with the axis of the rotor. This reduces friction to the minimum. It also provides a constantly varying surface of contact between the faces of each blade and the corresponding walls of the respective channels and ermits a rocking action of each blade relatlvely to its respective channel and to the axis of the rotor, so that all .blades instantly accurately accommodate themselves to their channels at every point in the travel of the rotor. This construction and line contact permitting rocking and sliding contact of the blades, also assures continuous contact between the outer face of each blade and the interior wall of the cylinder.

The rotor 2 is provided interiorly with a series of ducts 8 in three d-ifl'erent planes as shown in Fig. 2 for example. The ducts 8 provide intercommunication between the channels 3 at the back of the blades 7, and a common pressure is thus maintained on the inside of said blades. In order to maintain a requisite pressure at the inside of the blades, there. is arranged in the rotor 2 between the channels, a series of non-return ball valves 9 or other suitable valves, which control the admission of fluid t'o-the middle series of ducts, although the valves may be fitted to the outer ducts if desired. The valve seatings 10 are screwed'or connected radially in the rotor 2, one or more being situated between neighboring blades 7 and controlling access to the said ducts by way of openings 11 or the like formed within the rotor 2. The said valve seatings may be formed with outer flanges 12 abutting against the bottom of recesses in the rotor 2 and therebyderive position and lie within the confines of the latter.

With this construction, should the fluid at the inside of the rotor fall below a certain pressure, the outside fluid forcing open the valves 9 passes to the interior of the rotor and presses the blades 7 against the walls of the cylinder .4.

When the machine is to be used as a prime mover, motor, or the like, the shaft 1 may be disposed as shown above the centre of the cylinder 4, so that the blades 7 which are at the lower half of the rotor 2 when the machine is at rest, or rotating at relatively slow speed, will tend to move out of the channels against the boreof the cylinder 4 and'be positioned for action by the fluid pressure.

@ nee half of the rotor 2 will tend to sink into their channels 3 when the machine is at rest and when same is bein rotated at a relatively slow speed. By t is means, the rotor 2 with its blades 7 may be rotated without, imparting motion to the fluid medium or tending to impart only a relatively small motion thereto. Thus the prime mover which may be utilized to drive the machine as a power transmitter may be easily started up and the necessity for clutch devices or the like may be obviated. li fhen the speed oi the machine is increased, however, centrifugal torcewill cause the blades 7 to move outwards until they bear against the bore of the c linder 4t, thus obtaining the maximum in ct and discharge of the fluid medium. By this action, the movement imparted to the said medium may be caused to commence gradually and without shoclr.

Alternatively, the rotor may be devoid of non-return valves.

In a modified form shown in Fig. 3, flem ible plates 13 or the like are attached to the blades 7, said plates being disposed at the sides thereof and adapted to press closel against the inside faces of the c annels it by any pressure which may be set up in the un In the modified form shown in Flo. d, the flexible plates 13 are formed "integrally with the blades 7 and are adapted to engage the inside races or the channels 3 as atomsaiill lln the modified form shown in Fig. 5, the inner part 7 or the blades 7 is shown as convexed.

The eccentricity or the rotor shaft 1 in relation to the cylinder may be such that the interior space or the rotor 2 may remain at a constant capacity in all oositions which the said rotor may assume w ilst rotating.

1 The channels and blades may be provided with hard metal liners it required.
